The chain's "Breakfast for Dessert" promotion, which runs through April 25, features frozen yogurt flavors such as Maple Bacon, Iced Cinnamon Roll, Cup of Coffee, Orange Juice Sorbet and Frozen Hot Chocolate.

There are also breakfast-themed toppings, including cereal, fruit and kosher bacon bites.

David Kahn, Yogurt Mountain's president and founder, said the idea for the promotion started when the company was preparing to roll out its new Maple Bacon flavor. They decided to have fun with it.

"Chocolate and vanilla is chocolate and vanilla," he said. "We wanted something that was a little fun and different for our customers."

Along with the breakfast theme, Yogurt Mountain stores have been made over with a 1950s diner-like feel. There's a chalkboard door decal and a menu on the windows. Employees also wear white diner hats.

Frozen yogurt became hot again around Birmingham in the late 2000s, with stores popping up all over the metro area. A number of them have since closed but some have continued to thrive. The trend has been fueled by local start-ups and national chains alike.
